And step 300, in the sorting process, the organic perishable garbage is collected in a concentrated mode, and the organic perishable garbage is subjected to classified digestion treatment by utilizing organisms and microorganisms.
The biological-microorganism fractional digestion treatment refers to that in a biological-microorganism fractional digestion system, nutrients in organic perishable garbage are absorbed by biological culture digestion, and then excreta generated in the biological growth process are concentrated to perform aerobic composting by microorganisms.
In this example, the hermetia illucens can be used for the bio-digestion treatment. Pretreating the collected organic corrosion-prone garbage, crushing large garbage in the organic corrosion-prone garbage, and carrying out solid-liquid separation and oil-water separation on the kitchen garbage. The organic perishable garbage obtained after separation is in a slurry state, the water content of solid matters of the organic perishable garbage is about 70%, and the maximum particle size of the organic perishable garbage after crushing is less than 20mm, so that the black soldier fly can be easily absorbed and digested. Meanwhile, the liquid part obtained by oil-water separation enters a high-pressure liquid storage tank and is pressurized to be made into spray, so that the spray is used for material water supplementing and regulating the humidity of the propagation environment of the hermetia illucens, the recycling of waste water is realized, the discharge is avoided, the environment is not easy to pollute, and the cost for purifying the waste water is saved. Meanwhile, the accumulation of salt in the final product protein feed and the Tabanus manure organic fertilizer is reduced.
In the process of utilizing the hermetia illucens to digest the organic perishable garbage, a special hermetia illucens culture workshop 700 is established, and the organic perishable garbage is transported to the culture workshop, so that centralized management is facilitated. In the process of converting the hermetia illucens into the organic perishable garbage, the powerful feeding and digestion capacities of the hermetia illucens larvae are utilized to convert the organic perishable garbage into high-quality animal proteins. The black soldier fly is digested to treat organic perishable garbage, which is to degrade biomacromolecules into biomacromolecules in vivo and assemble the biomacromolecules into biomacromolecules (protein, grease, chitosan and the like) of the black soldier fly, and the organic perishable garbage still exists in the value of the biomacromolecules after the homology risk is eliminated, so that the added value is high. In the conversion process, as no obvious anaerobic link exists, the production of malodorous gas (hydrogen sulfide and mercaptans) is less, and the malodorous gas is mainly ammonia nitrogen tail gas and is easy to control. The filtrate produced in the cultivation workshop is collected and recycled for cultivation in the cultivation workshop, namely the black soldier fly is utilized to digest sewage, so that the sewage is not discharged, the environmental pollution is reduced, and the sewage purification cost is saved. The protein and fat content of the hermetia illucens are far higher than that of fish meal and soybean meal, and the hermetia illucens can be used as a high-efficiency feed additive for various animals.
After the hermetia illucens is converted into the organic perishable garbage, the organic peristalsis illucens is separated by utilizing an insect material screening device, so that high-quality hermetia illucens fresh insect and insect manure organic fertilizer products can be obtained. Mixing the insect manure organic fertilizer product and the residual organic perishable garbage, and placing the mixture in a fermentation tank for aerobic composting treatment. In the aerobic fermentation process, the materials in the fermentation tank are periodically turned over and enriched with oxygen by utilizing the propelling movement of the turning over machine, and an aeration system is arranged at the bottom of the fermentation tank, so that the organic materials are quickly decomposed. The primary product is crushed, screened and added with nutrient and biological bacteria to prepare organic fertilizer series products, and the products are delivered for sale after being inspected to reach the standard. Colleagues, a small amount of composting tail gas is sprayed and purified through the atomization of the deodorizing bacteria liquid. The microbial aerobic composting treatment is adopted, the microbial digestion product is a refined organic fertilizer, the total nutrient is high (the nitrogen, phosphorus and potassium accounts for more than 9%), the death rate of heavy metals and roundworm eggs, and the value of escherichia coli is far lower than the NY 525-2012 standard limit value, and the crop yield and the insect-proof and pest-resistant capability can be improved when the microbial aerobic composting treatment is applied to farmlands.
The NY 525-2012 standard refers to the agricultural industry standard of the people's republic of China-the organic fertilizer standard.
In this embodiment, alternatively, in order to ensure that a sufficient amount and quality of hermetia illucens are converted into organic perishable garbage, a breeding workshop is provided to perform breeding of hermetia illucens population. In the hermetia illucens cultivation process, the temperature, humidity and illumination conditions of a breeding workshop are controlled, and an ideal natural environment is provided for growth of the hermetia illucens, so that the hermetia illucens population is continuously, stably and massively propagated. In the hermetia illucens cultivation process, the population reproduction cycle is maintained by keeping 0.8% -1.2% of the hermetia illucens larvae, and the rest 99.2% -98.8% of the hermetia illucens larvae are used for transforming organic perishable garbage.
In other embodiments, the bio-microorganism staged digestion may be of an insect organism such as earthworm breeding or cockroach breeding, and the digestion of the organic perishable garbage may be achieved as well, and the organic perishable garbage may be converted into insect proteins for storage in the insect organism. And (3) fermenting excrement generated in the insect biological growth process by utilizing aerobic compost, wherein a final product is a refined organic fertilizer.
